Psy took part in a Reddit AMA ('Ask Me Anything') session on Wednesday (October 24), and when asked how his loved ones reacted to his sudden fame, he said: "They are normal people, so they are freaked out because it's way too fast and way too far. Even I myself get freaked out a little bit about it. We were not ready for this."

He added: "I feel weird about all the fans because they are so worldwide. I cannot really believe it yet."

Psy additionally revealed that the elevator sequence in the 'Gangnam Style' video was ad libbed, saying: "Nong Chul is the name of the elevator guy, and he is [a] very famous comedian in Korea. That is a very popular dirty move he has been doing for six years, and I asked him to do it in my video. If I [was] underneath, it would be dirtier!

"We only did 2 to 3 takes, and everyone on the video set was crying from laughing. Definitely my favorite scene in the video."

The singer and rapper also joked during the Q&A session that his hair "only looks perfect on TV" and said that he manages to maintain his composure during dance routines "because I'm serious about my dancing".
